I have an SB8200 used to Link to COX.

The modem keeps dropping out and has to reconnect.  Called Cox, they think the modem is bad (the associate didn’t seem to have a full handle on the situation).  

Question is the Event logs show the following when it drops out:

Do these events indicate a problem with COX or the Modem?

Thanks,

SB8200 is just a cable modem its a plug and play device so if the internet drops on direct connection we need to check the cable signal level of the modem to isolate the issue so please do monitor the connection by connecting device directly to the modem without router. 

Monitor whether the LED lights on the modem going off or changing color when internet drops
